Nonlipophilic corynebacteria associated with clinical and subclinical mastitis in dairy cows were found to belong to four species: Corynebacterium amycolatum, Corynebacterium ulcerans, Corynebacterium pseudotuberculosis, and Corynebacterium minutissimum. These species may easily be confused. However, clear-cut differences between C. ulcerans and C. pseudotuberculosis were found in their acid production from maltotriose and ethylene glycol, susceptibility to vibriostatic agent O129, and alkaline phosphatase. Absence of growth at 20 degrees C and lack of alpha-glucosidase and 4MU-alpha-D-glycoside hydrolysis activity differentiated C. amycolatum from C. pseudotuberculosis and C. ulcerans. The mastitis C. pseudotuberculosis strains differed from the biovar equi and ovis reference strains and from caprine field strains in their colony morphologies and in their reduced inhibitory activity on staphylococcal beta-hemolysin. C. amycolatum was the most frequently isolated nonlipophilic corynebacterium.

The aim of the study was to evaluate enzymatic activities of yeasts isolated from inflammatory mammary secretion. The yeasts isolated from cows with clinical and sub-clinical mastitis (134 strains) included: Candida krusei (62 strains), Candida kefyr (48 strains), Candida lusitaniae (17 strains) and Candida famata (7 strains). The API ZYM system was used containing substrates to assess 19 hydrolytic enzymes. Substantial differences in the number and activity of hydrolyses were demonstrated in individual species. In Candida krusei, acid phosphatase showed the highest activity (4.36 points), in Candida kefyr and Candida lusitaniae--leucine arylamidase (4.93 and 4.25 points, respectively), in Candida famata--alpha-glucosidase (4.75 points). No activity of trypsin, chymotrypsin, alpha-galactosidase, beta-glucuronidase, alpha-mannosidase or alpha-fucosidase was observed in any of the yeasts examined.
